Oil Cooler Assembly Inspection and Repair
This engine features a “removable-bundle” type oil cooler. Periodic visual inspection of the oil cooler will indicate condition of gaskets, O-ring and core. If a problem exists, these components can be serviced separately rather than replaced as an assembly.
DESCRIPTION The oil cooler assembly is located near the left front of the engine. Engine coolant from the heat exchanger flows through the lower tube and hose assembly, into a chamber in the oil cooler. The coolant then flows into the water pump. The oil pump sends engine oil through the inlet port of the oil cooler into the cooling chamber. Heat from the engine oil is transferred through the chamber walls to the engine coolant. Cooled oil
The presence of engine oil in the engine coolant may indicate internal engine problems or worn, loosened or damaged parts within the oil cooler. Continued operation under these conditions may result in severe engine damage. 239
